Purpose: There is a difficulty in Environmental Stress Screening (ESS) test design for weapon system's electrical/electronic components/products in small and medium-sized enterprises. To overcome this difficulty, I propose an easy ESS test design approach algorithm that is optimized with only one environment tolerance design information parameter (${\Delta}T$). Methods: To propose the mass production weapon system ESS test design for cost-effective optimization, I define an optimum cost-effective mathematical model ESS test algorithm model based on modified MIL-HDBK-344, MIL-HDBK-2164 and DTIC Technical Report 2477. Results: I clearly confirmed and obtained the quantitative data of ESS effectiveness and cost optimization along our ESS test design algorithm through the practical case. I will expect that proposed ESS test method is used for ESS process improvement activity and cost cutting of mass production weapon system manufacturing cost in small and medium-sized enterprises. Conclusion: In order to compare the effectiveness of the proposed algorithm, I compared the effectiveness of the existing ESS test and the proposed algorithm ESS test based on the existing weapon system circuit card assembly for signal processing. As a result of the comparison, it was confirmed that the test time was reduced from 573.0 minutes to 517.2minutes (9.74% less than existing test time).

To development of the low toxic preservatives, we prepared 29 kinds of chemicals using dinotefuran of low toxic insecticide, IPBC and propiconazol of fungicide, and clove oil has fungicidal activity, but is harmless to humans. It was conducted to investigate the inhibitory effectiveness of mycelial growth and anti-mold effectiveness to treated PDA medium and wood specimen with prepared chemicals. It was not showed anti-mold effectiveness that solvent and emulsifier form preservatives. Therefor, we thought that only four component, dinotefuran, IPBC, propiconazol and clove oil, has anti-mold effectiveness. In the PDA medium test, the preservative which has much IPBC showed high anti-mold effectiveness. By the wood specimen test, it was known that many prepared preservatives which showed good inhibitory effectiveness of mycelial growth in the PDA medium test, have not anti-mold effectiveness. Of all prepared preservatives in this study, only three preservatives containing dinotefuran and IPBC, or adding clove oil appeared the excellent anti-mold effectiveness.

Purpose: The purposes of the study were to examine whether nurses' followership style influence organizational effectiveness and to test the model of organizational effectiveness including the factors of nursing organizational culture, leadership style, and followership style. Methods: Data were collected from July 10th to september 20th in 2006 from 451 nurses working in four acute care hospitals. Data analysis were performed by Chi-square test, ANOVA, Duncan test, Pearson Correlation, and maximum likelihood estimation, using the SAS and LISREL 8.30 program. Results: The findings showed that the types of nurses' followership were classified as passive (21.1%), alienated (8.2%), conformist (16.4%), pragmatist (35.9%), and effective style (18.4%). There was significant difference in the organizational effectiveness among the nurses with different followership styles. In testing the path model, transformational, transactional leadership directly influenced followership style. Followership directly influenced organizational effectiveness. Conclusion: The overall fitness of the model was good, evidenced by general fitness index (GFI)=.94, adjusted goodness of fitness index (AGFI)=.82, and root mean square residual (RMSEA)=.06. Based on the findings, it is recommended to develop a program for enhancing effective followership in nursing organization.

PURPOSES: The purpose of this study was to investigate the disintegration mechanism of concrete due to the infiltration of the moisture to the milling overlay pavement and to come up with a method to minimize the disintegration as well as verifying the effectiveness of the edge sealing and Fogseal method. METHODS : This study investigated the distress mechanism due to the infiltrated moisture remaining in the milling overlay pavement through chloride freezing test and verified the effectiveness of the sealing of the milling edge and fog seal methods, which have been devised to minimize the moisture infiltration, through laboratory water permeability test. Additionally, long-term pavement performance was compared for the effectiveness of the proposed method through under loading test, and field water permeability test was carried out to verify the field applicability of the proposed method. RESULTS: The result of the research confirmed that chloride deteriorates the concrete surface through disintegration and lowers its strength and that the laboratory moisture infiltration test verified the effectiveness of the milling edge sealing and fog seal methods in the deterrence of moisture infiltration to the overlay pavement with excellent long-term performance of the pavement treated with the proposed method. Although the field water permeability test revealed some deterrence of moisture infiltration of the milling edge sealing and fog seal methods to a certain extent, the difference was a little. CONCLUSIONS: The milling edge sealing and fog seal methods are limited in their effectiveness for the cases of improvident compaction management or mixture with large void, and it is believed that installation of subsurface drainage is more effective in these cases.

The shielding enclosure is very essential device to test the electromagnetic wave power generated by various RF equipments. Some standards for the shielding enclosures were established to test them in right method. Generally, There are IEEE-STD-299 and MIL-STD-285 and NSA-65-6 of the method for measuring the effectiveness of shielding enclosures, the IEEE-STD-299 combined MIL-STD-285 and NSA-65-6 about the method for measuring shielding effectiveness(SE) about 1969 years, but, the measurement point of 299 proposal is many points(including shielding wall, seam, coner beat, shielding door, etc) and demand long time of measurement. To improve SE test method for shielding enclosures was studied and suggested to develop a proper test procedure. First, we measure reference level as frequency range and H/V polarization, secondly, measure leakage point, and finally, measure shield effect and calculate SE. Our method has a merit of the less measurement point than IEEE-STD-299, and shorten time than 299, and define representation SE of shielding enclosure effectively.

The purposes of this research were to develop a family life education program for single-parent families in rural area and to investigate the effectiveness of education through continuous tests.For these objectives, the concurrent-type program for single-parent families that emphasized communication skills, psychological strategies, and the importance of social support system was constructed. The effectiveness of the program was evaluated by pre-, post- and delayed test through 88 single parents and their children and it was analyzed by paired t-test. The results suggested that the program was effective in improving self-esteem, self-confidence and in decreasing depression. This effectiveness was more in single-father families than single-mother families. But especially in children this effectiveness was diminished as times passed. For maintaining this effectiveness in program, more frequent and continuous following education was demanded.

This study intended to test the structure of the latent factor of an effectiveness scale and the stability of invariance across groups of students' classifications (gender and levels of education). In the large, non-clinical sample (850), students completed the effectiveness scale. The (CFA) confirmatory factor analysis was used to investigate the factor-structure of the measure, and multiple-group confirmatory factor analysis (MGCFA) model was used to test the stability of invariance across groups of students' classifications. The findings of the CFA indicated support for the original four-factor model. Additional analyses of the MGCFA method support the measurement (configural, metric and strong) invariant and practical invariant components of this model. There was an invariant across gender. There was partially invariant across groups of levels of education. The scale exists in groups of levels of education assess the same concepts of, excluding Items 15 and 10. Given that this study is the first investigation for the structure of the effectiveness scale.
